TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES BnEnLY, of the city and county of Worcester, State of Massachusetts, have invented a new and useful Improvement in` Operatingv the Shuttle-Boxes of. Looms; and I do hereby declare the following to be a full, clear, and exa-ct description of the construction and operation of the same, reference being had to the accompanying drawings, in whiehi Figure 1 is a view of my invention, applied to a loom with movable shuttle-boxes.

Figure 2 shows a front viewof the boxes, and the means of holding them when raised Figure 3 shows details of the let-offer dropping-apparatus.

Figure 4 shows a back view of the lifters and slides.

Figure 5 shows a. plan of the same with the carrier- The same letters indicating the same parts wherever they occur.

My invention relates to the changing of the shuttle-boxes of looms, in which more than one is used, and is 'designed to give complete control of them by the -pattern-chnin, and change from any cnc to any other one of the boxes that is desired.

In constructing my invention, I makel use of a pattern-chain, A, with 4its rolls, B B B, to lift the levers C C C C C C, somewhat in the common way. One of these levers, C', is connected to the dropping-apparatus or let-oi-D of the shuttle-boxes, and thc others are connected to the lifters F F F F F, which correspond in number to the number ofshuttle-boxes used, less one.

O O O O O are slides or blocks, sliding and turning on the bar G, when turned or lifted by the lifters into the position shown atvO O O', and are then moved by thecarrier H, which moves them along the bar G, and makes them move the lever I to gauge the position ofthe boxes.

J J are the boxes, of whichV I have shown six, which are support-cd bythe spring-catch L in the notches on rod K, the lower part of which has a collar, N, sliding up to a shoulder at n, and is connected to lever I.

To the spring-catch I connect a. lever, I), having a pendant-trip, R, hung to turn one way, and to work the lever L when moved the other, and place the tripping-shaft D with its arm, d, attached to a lever, operated by the chain and its arm, S, in such position that when raised it shall stand in the way of the pendant R, and

opera-te it.

The carrier H receives its motion from a crank, T, on the shaft U, and is so placed as to move freely over tbc slides O C Ol O C, when they are not lifted, and when lifted they are carried forward and returned to place by it, thc shaft U having the saine motion as thc crank-shaft V.

The other parts ofthe loom may be of almost any common form or construction used for the various kinds of weaving wherein more than one shuttle is used. The slight variations cf such parts as need'any change to apply my invention to them, will appear to those skilled in making such looms without further invention, and therefore itis thought unnecessary to describe them more fully.

The operation is as follows:

The chain A being arranged-with the desired changes, it gives motion to the levers C C C C C, which raise the liftcrs F F F F F, elevating the slides C O O O C, and the carrier H, in going forward, moves them along the rod Gr, operating the .lever I, raising lthe Iboxes J the proper or required distance at or near the time of beating up, after which the carrier returns the slides O 0 0 O O, which, unless held up, fall into place, and the carrier passes freely over them.

The cust-off lever C', when raised, brings up the arm S in the path of the pendant It, and, a-s the lay moves back, the pendant turns,nnd passes the arm without moving the lever, but on beating up, it catches the arm and movcsthe lever P, releasing the catch L, and4 allowing theboxcs to drop to the position indicated by the numb'er of slides held forward by the carrier, the end of the levcr I rest-ing against the forward slide, or if the slides are all down, thc boxes fall to the upper or first-bon, and then if three slides are raised, as shown in fig.

1, the carrier, at its next movement, will move the lever I and raise the boxes three higher, bringing the fourth into position; thus the number of slides raised determines the change, and these being governed by the chain enables me to make any change desired.

It is evident that the parts composing mybox-motion cajn be made of such size as to apply to the same end of the loom as thcharness-motion to either end or to both end-s, by simply duplicating the parts and connecting them together by suitable connections not requiring a description. If desired, the boxes of both ends may be moved by one pattern-mechan ism, and the slides maybe arranged with springsor levers to insure their falling to place, if thought best, and other variations made without departing from the principles of my lnvention. l

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of slides O, controlled bypattern-mechanism, with a carrier, as and for the purposes set forth.

2.*The combination of the lifters, slides O O, and carrier H, for operating the boxes, substantially as described. A

3. The combination of a sliding spring-catch, L, pendant R, and notched box-rod K, substantially as set forth.

4. The combination of the cast-oli' lever P, having a pendant, R, with the ytripping-arm S, and its operative mechanism, substantiallyas described.

5. The combination of the cast-off and raising-apparatus, consisting of the litters, slides, carrier, and their connections, as described, whereby I can change theboxes at will, on'one or both ends of the loom, substantially as set forth. v

' JAMES BRIERLY.
